VBaa; known that LrERCY Bf Bestimmt,

a :citizen: of ythe` jUnited States, residing at Akron-in .the ,countyllof Summit and State 4. `,of fOhio,A have invented `c'ertainnew; and useful Improvements in FasteningDevi'ces for Vehi cle-'I`ires`,1y of which .thej 1following' is a specification. ,1;

This invention relates tofthe artof veliiclef-tires,fand pertains more' especially to new and improved means for securing the tires on the rims of wheels. In the case of automobile and truck..tiresgespecially, which are subject to comparatively frequent repair and renewal, it is desirable to render such tires easy-of application and removal to and from the wheel, and consequently the matter of fastening orretainingdevices for such tires has latterly assumed considerable importance. Y

The object of my invention is to provide a new and simplified means for securely fasteninga'tire on the wheel while at the same time permitting its easy and ready withdrawal for repair or substitution by a new tire; andto this end my invention compre- Y hends as its principal novel feat-ure the provisionof a'removabletire-seating rim adapted to be applied sidewise over the permanent rimor felly of the wheel in combination with coperating devices carriedby said removable rim and permanent rim or telly,`

rpectively, for 'detachably securing the former on the latter.

I have illustrated the principle of my invention in several forms in which the same may find expression in the accompanying drawings, wherein,-

Figure 1 is a side elevational view of the rim and tire-portion of a wheel equipped with my improvements. F ig. 2 is an enlarged cross-sectional view through the tirel and felly of tliewheel. 3

In the accompanying drawings I have selected to illustrate my present improvements a form and .constructionof tire and tire-clamping lmeans disclosed in Letters Patent to James A. Swinehart, No. 624,992, granted-May 1G, 1899; but it will be understood that .the principle of my invention is equally applicable to other forms of tire, whether solid or pneumatic. l l

Referring to Figs. 1 and 2, l0 may designate the tire proper, 11 the transverse pins embedded in the baseof the tire, 12 a stand-.

ard channel-shaped-rim, and l13 the retainin-g side wires, all substantially as illustrated in the Letters Patent hereinabove referred to. In the said patent, however, the rim corresponding to the rim 12 is shrunk on thel the channel rim 12 is designed to be readily removable relatively to the wheel rim, but constitutes a -iixed member of the tire, being inthe nature of a sup lemental rim.-

14' indicates the Woo en felly of the wheel,

which is surrounded by a plain metal band or rim 15 shrunk thereon. 16 and 17 designate, respectively, a pairof side-{ianger members that are secured to the felly by throughbolts 18'and nuts 19; these side-flanges being simply plain rings apertured for the passageof the through-bolts 18 andat their outer margins projecting somewhat beyond th'e rim 15, with their inner walls vertical or at right angles to the latter, whereby to constitute retaining devices as hereinafter described. Secured to the inner periphery ofthe supplemental rim 12 as by rivets 20 is a ring or band 21 that may be hollowed out onfits inner side so as to present simply two lines of contact at 22 with the rim 15, which lessens 'friction and reduces the work required in sliding the tire on and off the rim 15. This ring or band 21 constitutes the cooperating member of the retaining means, for which purpose its Opposite edges are made vertical to abut squarely against the projecting inner walls of the retaining flanges 1G and 17, as shown at 23 in Fig. 2.

A To remove the tire constructed as shown and described it is necessary only to remove the nuts 19 and withdraw the adjacent flange Y17, whereupon the tire with its attached channel-rim and base-member, may be withdrawn laterally of the rim or felly; and the simple reverse of these operations elects the application of the tire to the rim or chine is required to spring the side Wires 13 into place When anew tire is to be applied to the Wheel, and of course this same advantage holds truein the ease of tires having internal or other machine-operated retaining devices.

l am aafare that it is old broadly to ern.- ploy a supplemental rim that is, detachable with the tire relatively to the permanent rim or telly of the Wheel, and also te employ in connection therewith retaining means in the nature of sidellange directly engaging a supplemental rim of special construction.

I t will be observed thatin my invention shown and described the retaining side- 'tianges do not directly engage the supple mental or tire-carrying'rim, nor do they require any special construction of such supplemental or tire-carrying rim; but rather they engage a coperating fastening memfit is secured to the inner periphery supplemental, or tire-carrying `'rim suitably shaped to coperate With the ng flanges. My invention is thus adapted for use with any standard forms 0f tire-carrying rim, and does not require modiiictien or special formation of the latter.

l claim:

ln a device of the eharaete'r described, the combination of a tire-seating rim, anda wheel-rim having a Cylindrical external :Suracelof a ring seeured'te the inner periphery 01" said tire-seating rim, said ring being hollow on the central part of its inner side and having a pair of inwardly-directed transversely-convex ribs with line contacts on said Wheel riln7 said ring having outer edges substantially flush with the side-faces of said Wheel-rim, side tianges projecting radially beyond the sides of said Wheel-rim and engaging'said opposite edges of said ring, and through-bolts detachably securing at least one of said'side flanges to said. wheel-rim, substantially as described.
